Specification of Letters Patent. Patented Sept, 1914,

Application filed June 12, 1912. Serial No. 703,346.

ToaZZ whom it may concern:

Be it known that I, PHILIP HAAS, citizen of theUnited States, residing at Dayton, 1n the countyof Montgomeryand State of Ohio, have invented certain; new and useful Improvements in Flushing Devices for Water-Closets; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

novel features .My present invention relates to the class of automatic flushing devices for water closetsandconsists in an improved construction of valve mechanism releasing and controlling thepassage of water to the bowl.

In thedrawings I have shown the best form in which I have contemplated embodying my invention and the said invention is hereinafter fully described and its pointed out in the specification and claims. 1 j

In my saididrawings, Figure l is a vertical elevation partly in section. Fig. 2 is a horizontal section on. dotted line 22, Fig. 1. Fig. 3 is a vertical section on line 33, Fig. 1. I i-g. 4c is a'partial longitudinal vertical section of the main body or casing.

In these figures of drawing, A represents the casing or body of my improved flushing 1 valve or device, which is hollow and provided with a cylindrical pressure chamber a having a removablecap or closure G at its outer end. The casing is also provided with a cylindrical guiding chamber a in axial alinement with the pressure chamber of, which is closed by a simllar removable cap or closureG, Within the casing or valve body is a partition 44 disposed transversely to the axis of the pressure terposed between them, the said partition being provided with a central aperture a substantially in axial alinement with the axis of the pressurechamber and guiding chamber. The casing is also provided with an inlet chamber a which communicates by a passage a with theqguiding chamber, on one side of the partition, and the valve casing is also provided with an outlet chamber a which communicates by a passage a with the-pressure chamber a on the other side of the partition e 3 Within the pressure chamber is located a piston B fitted therein and provided" with a concentric stem 6,

.which is adjustable with respect to the pisy set nut Z2.

and screwed into a threaded aperture in the piston and secured in adjusted positioniby This. piston carries a valve B WhlCll is adapted to engage portions of the partitlon'ci surrounding the aperturect and close said aperture when the piston is at the inner end of the chamber. In the guiding chambera I provide aguiding body C wh ch fits easily therein and is preferably provided with a plurality of peripheral grooves or notches C? which afford a con' also carries on'its inner face a cylindrical valve B which projects beyond the valve 0 and. normally fits within the aperture a The guiding body C is movable with respect to. the piston, but is actuated by the stem 2) thereof, the said guiding body Chavmg a central bore or recess which receives the stem 6 with an easy fit so as to permit of relative movement between the. body C and the stem Z) longitudinally of the stem, as indicated in dotted lines in Fig. 2. The valve casing is also provided with a rounded projection D. .IVithin this projection is located the valve E and a passage 9 connects this .valve' with the inlet chamber a.

The valve E is mounted on a stem 6 extending above and below the valve. Below the valve this stem extends downward through a'passage (Z in the projection D and through a stuffing box at the bottom of the same. Below the stuiiing box the stem is provided with a cap 6 to be engaged when the valve E is to beraised. A spring f is provided to draw down the stem and close the valve when the stem is. released from the pressure which raises it. j

The passage (Z is connected by a passage g with the pressure chamber a in rear of the piston B and the passage 0? just below the valve E is enlarged downward to the said passage 9 so that when the valve is raised water will readily flow from the valve to thesaid passage. The remaining ton, in this instance being screw threaded portion of the passage 03 is of less size but still is larger than the stem of the valve and provides a reduced passage for water to flow through. A space d just above the stuffing box is connected with the water outlet y a pa a 9 The, operation of this device is as follows: The arrangement of the device is such that when pressure is placed upon the seat of ,the closet a part connected therewith (not shown) I will press upwardly upon the cap ,6 and raise the valve E. Water will then enter the passage 9 from the inlet chamber, pass below the valve E into the passage d anddownward in said passage and through the passage 9 into the pressure chamber a behind the piston B. The outer end of the 1 rod I) connected therewith normally rests at a predetermined distance from the bottom of the opening in the valve B and the movable guiding body G and, therefore, the piston and its connected valve will, at the time determined upon, move the said valve and movable guiding body 0. As soon as the valve B leaves the opening a water will flow from the inlet chamber a through the opening 03 down through the outlet chamber a intov the bowl for the preliminary flushing of the latter. This flow continues only until the valve 13 closes the opening (L This is only for a short time as the piston in this movement moves with considerable rapidity. When the valve B has closed the opening a the valve B will have been moved a distance away from the said opening. In this position ofthe parts no water passes to the bowl except such as passes downward through the passage cl around the stem of the valve E.

" Then the seat is relieved of pressure the valve E drops and closes the upper part of the passage drelieving the rear of the piston B from pressure. The pressure on the face oflvalve B forces this valve and piston backward as fast as the water in rear of said piston can flow out through the pas-i sages g, d, spaced into the water outlet.

'As soon as the valve B moves from the. opening a water from the water supply; flows through said opening into the chamber f, a and through the water outlet into the; This flow continues until the valve B closes the saidcopening This movement is caused by the drawi of the rod 5, the suction of the outflowingf main casing provided with a compression chamber at one endan'd a guiding-chamber bowl flushing the same.

current, and pressure of the water supply.

v The length of the flushing of the bowl is; regulate d by the distance vbetween the face :of the valve B and the valve B This. distance can be increased or diminished by adjusting the rod in the connected valve and piston body, and this can be accomplished at any time when the parts are in their normal position s by removing the cap Gr closing the outerend of the pressure chainb er a .The aperture a being then closed by the v'alveB the piston body can now be removed, the lock nut 79 loosened and the rod 6 moved to the-positiondesired and secured by the lock nut.
